Student: “How did you get from there to there?” Teacher: “Where?” Student: “That second line, right there.” Teacher: “There?” Student: “No, nevermind.”

I actually saw that dialog going on in class yesterday. I thought about it for awhile, and I realized several times I’ve not bothered asking a question because it would be too difficult to point out where I’m talking about.

My solution: I should start carrying a laser pointer with me. I have three classes of at least 150 students, and having a laser pointer with me would probably help motivate me to ask questions more often and get more out of my university experience.
